Konstruktion av fackla för biogas
Värmekollektor in Sunne is a company whose main occupation is to collect the gas produced inlandfills. The gas contains about 50 % of Methane which is a greenhouse gas 20 times worse than CO2and should therefore not be allowed to leak into the atmosphere. The Methane is in as large amount aspossible used in different plants for example heating of households. But there are occasions when aflare is needed to burn the excess gas at standstills or testing of new landfills. The Flare only burns themethane to reduce the hazarder?s effect of the environment, it does not take advantage of the energy inthe gasThe goal of this master thesis was for me to create a foundation for an in-house production offlares for Värmekollektor.
Svenskproducerat proteinfoder till slaktsvin
Soybean meal from South America is the most common protein feed used for animal production in Sweden. Production of soybean has negative effects on the environment and the transports from South America to Sweden causes considerable CO2 emissions. Therefore it is a growing interest in locally produced protein feed in Sweden. Protein feeds that are possible to grow in Sweden are rapeseed, peas, faba beans and lupins. Those are adapted to the Nordic climate and are perfect to grow in cereal rotations.
Konceptstudie av Waste Heat Recovery System på Tunga Fordon
In today?s fast growing and closely connected society, a reliable and energy efficient transportation system is more than ever desirable. Nowadays the significant part of the transportation sector?s energy demand is supplied by fossil fuels.Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat losses in the exhaust and cooling systems.
Ledarskap i ett Lean perspektiv : vad i sitt ledarskap behöver lantbrukarna utveckla?
The essay is written at the request of Nyköping municipality park management by PatRadestedt who wanted a design proposal for one of the five courtyards at the Tessin Schoolin Nyköping. The Tessin School is located 2 miles from the center of Nyköping and the schoolhouses approximately 900 students. To make a design proposal for the courtyard that lies atthe canteen I decided from the outset that I wanted to take some of the Tessin SchoolStudents' opinions and wishes regarding their own outdoor spaces. I had a workshop witheight students from the arts program with the image orientation in which they had to drawand tell them what they wanted to do in the courtyard. The outcome of the workshop, Iused to move forward in my future work with a concept that fit into the environment, wethen apply it in my final design proposal.
Akka. Ett skrivbord för hemmet anpassat för rullstolsburna.
A woman is dying of cancer, she refuses to use her walking aid. Because she is embarrassed. This means she can?t leave her house, and her last days become very limited.Why do we act like this?Can the view we have of products adapted for disabled be changed by working with colour, texture, form and materials?There are many products adapted for disabled, the products often have a good function and well developed ergonomic aspects but the visual aspect leaves a lot to wish for. There is neither effort nor money put in to the exterior design of most of these products.A lot of the solutions that are invented for adapted products can be used in design of ?regular? products.Why should we then divide products in to adapted and non-adapted.
CORRELATION BETWEEN ENDOMETRIAL MARKERS AND PREGNANCYOUTCOME IN WOMEN WITH UNEXPLAINED INFERTILITY
ABSTRACTA defect implantation process is the major reason for unexplained infertility. Estrogen andprogesterone are steroid hormones preparing the endometrium for implantation. They mediatetheir effect through their receptors: estrogen receptor alpha and beta and progesteronereceptor A and B, respectively. Leukemia inhibitory factor (LIF), which is also important forimplantation, mediates its effect through LIF receptor and the coreceptor, gp130, and is downregulated by suppressors of cytokine signaling 1. The aim of the study was to compare thelevels of the steroid hormone receptors and LIF related factors in the endometrium of twogroups of women with the diagnosis unexplained infertility: one that became pregnant afterassisted reproduction and one that did not become pregnant.
Cirkushallen i Alby :
Ad Astra är en cirkushall, högt beläget på en skogsbeklädd kulle ca 10 minuter från Alby centrum. Här samlas hela Cirkus Cirkörs verksamhet under ett tak: elever, lärare, administration och besökare.Promenadvägen från Albys tunnelbana leder fram till ett torg med den nya byggnaden som fond. Ett strikt grid av 58 stålpelare definierar ett uterum på byggnadens tak som sluttar upp mot en kopparkub bland träden. Här skapas möjligheter till allt från utomhusföreställningar till picknick i ett landskap som subtilt smälter samman med den bakomliggande skogen. Gränsen mellan natur och struktur suddas ut samtidigt som taket ger en oöverträffad utsikt över Alby och Albysjön.Internt är byggnaden tvådelad med en publik, öppen del och en sluten,flexibel hallösning.
Kundfokuserad miljökommunikation med CRM-system : En Fallstudie hos Green Cargo
BackgroundToday a common approach to solve a complicated problem is to assemble a temporary workforce in order to solve the problem by working together within a project. One of the difficulties with working in projects is to maintain the planned budget. Working hours and costs are often exceeded. Many companies presume that any certain project will succeed, a presumption that leads companies not to anticipate risks involved in a project. In companies today there is seldom time for evaluation or moderation of a project, in order to have time for evaluation there is a great need for an adequate planning of the project.IntentThe intention with this study is to create a model for planning, budgeting and evaluation of projects within consultancy companies.MethodWith the help of interviews and discussions within the group Hamnar och Byggkonstruktioner at Sweco has evidence to present a proposal on planning, budgeting and monitoring been developed.ResultsA model has been developed to ease for consultancy companies to plan, budget, monitor and evaluate projects.
Ekologisk dagvattenhantering på parkeringsytor : Lösningsförslag för Eurostop köpcentrum i Halmstad
Stormwater from trafficked areas often contains high pollution levels. In traditional stormwater management design, stormwater is first transported away through piped networks, and then in most cases passes through oil separators before finally reaching the recipients. While this traditional method removes certain pollutants from the stormwater, it does not reduce the total flow, as in the case of ecological stormwater management. In the ecological method the stormwater is not simply transported away, but is recirculated through infiltration, percolation, and detention. The aim of this study is to investigate possible advantages of ecological management designs, in contrast to traditional management.
Alternativa drivmedel i den svenska vägtrafiken år 2030 : En utvärdering av den svenska regeringens målbilder
The Swedish government has set up the overall goal that no net emissions of greenhouse gases can occur after 2050. A sub-target has been developed for road transports which states that the use of fossil fuels must be reduced with 80% to 2030 in order to be completely abolished to 2050. A public inquiry mapping how this can be achieved was handed in to the government late in 2013. The use of alternative fuels for road transport, both biofuels and electricity, is expected to give the biggest contribution to the reduction of the use of fossil fuels. The inquiry sets up a number of goals for how much the use of alternative fuels must increase to 2030 in order to reach the overall goal and which instruments that are needed in order to do so.The aim of this thesis is to evaluate how these goals can be reached and what the most likely obstacles that may hinder the reaching of these goals may be.
Ökad återvinning i modebranschen : försörjningskedjans hinder och möjligheter inom produktutveckling
En ökad textilkonsumtion har lett fram till en problematik kring miljöpåverkan på grund av den ökade mängden använda textilier som ska hanteras efter produkternas död. För att ta till vara på de dyrbara resurser som har använts för att skapa textila produkter, har intresset för återvinning av textila fibrer ökat. Forskningen inom återvinning av bomullsfibrer har däremot inte kommit tillräckligt långt för att produktion av återvunna fibrer av hög kvalité ska kunna göras storskalig. Detta speciellt eftersom problem med exempelvis blandfibrer och separerbarhet försvårar arbetet. Det finns förändringar som kan göras av modeföretag i produktutvecklingsfasen redan idag, vilka kan underlätta återvinningsprocessen och syftar till att skapa ett slutet system i framtiden.
"Underhållsfria fönster" : I vilken utsträckning är dagens "underhållsfria" fönster underhållsfria och hur ser man
AbstractThe aim of this examination paper is to get an overview on the ?no-maintenance? windowsthat exist on the Swedish market, like plastic and aluminium windows.By way of introduction the reader gets knowledge in the background and problemformulatethat this subject has. This introduction explains why it has become so popular to changeyour windows into plastic- and aluminium windows and there is an existing scepticismagainst PVC and aluminium as construction material for windows.The main part of this report is constructed by segments of interviews where bothproducers of windows and stakeholders gets to answer questions about their viewing onno-maintenance windows from a material and construction point of view and where theproduction is headed to in the future. This is followed by an evaluation of a questionnaireon how pleased the house owners that changed their old windows to no-maintenancewindows are, followed by an inspection of windows made up from wood and an aluminiumclothing, windows made from only aluminium and PVC-based windows. It ends with atheory part about the materials PVC and metal based upon facts included in literature.By reading this report you can draw the conclusion that no window can be entirely nonmaintenancebut that the materials PVC and aluminium still are good substitutes for woodto lessen the maintenance..

En man och hans ?pplen: en fallstudie av Carl Str?mbergs ?ppeltr?dg?rd
This bachelor?s thesis studies Carl Str?mbergs ?ppeltr?dg?rd, a private garden consisting of a large number of apple trees and varieties. The garden is located outside ?rebro, in N?rke, and is owned by a unit owner association whose goal is to preserve and determine the varieties. Through interviews, articles, site visits and documents from Carl Str?mberg, the purpose have been to get an understanding of who Carl Str?mberg was, how he collected the apple varieties and how that process was affected by the climate amongst apple growing and pomology during that time.
Vem styr bostadsbyggandet i Nacka och Södertälje? : Vilka aktörer påverkar slutresultatet?
Who runs the development? A comparative study of the construction of residential buildings in Nacka and Södertälje.The aim of this study is to identify actors involved in the initiation and implementation of residential house construction in two Swedish municipalities. This means who is taking initiative for new residential buildings, who affects the planning process, who finances these new buildings and who builds them. By exploring empiric material from the municipalities of Nacka and Södertälje, the above questions will be answered and by referring to pluralism, growth machine theory and regime theory a link to general theories of political science is made. The results found show that the analysed municipalities have quite different possibilities for acting and that these backgrounds are also important for which actors will take initiative for new residential buildings and which actors will be allowed to state their opinion during the planning process.
